Cognite Reveal: Cannot handle Large Point CloudsNew

Cognite RevealWe are being told that our models need to be downsampled which is resulting in better performance in CDF but poor quality on the viewer. We have consistently noticed that we are unable to have one large point cloud together in the viewer and also the viewing quality is very poor compared to what laser scanning vendor solutions show. I need some attention on this from Product?Why should we downsample and decrease the density of the Point Cloud? does not appear to be the right thing to doWhy should we chop up the 3D model in pieces?

Executing transformation from Cognite Function

Is it a good practice to execute transformations from a Cognite Function?Our team implemented a Cognite Function which executes transformations on tables from Cognite RAW. We chose this solution as we wanted to parametrize the SQL query of the transformation, essentially applying a different filter on raw tables every time.Also, it would easier for the end user, e.g. a plant operator, to provide a JSON input to the function then to edit the query every time in multiple locations. E.g., if the JSON is:{ "plant": "Plant.1", "equipment": "equipment.1"}the user can just change the ID for the plant and equipment. Furthermore, these values can be validated by the function before making the replacements in the query and executing the updated transformations.Let me know your thoughts!

SAP Connectors - similar to MS AzureGathering Interest

In CAB 03/23 the gap about SAP connectors were discussed, now below article reached me (MS announcement). Hearing the details of SAP CDC the first time as of this article, I guess this is what’s actually missing in standard CDF, right? When/How this can get implemented on Cognite side?“General Availability of SAP CDC support in Azure Data Factory and Azure Synapse Analytics.”SAP BW is one of the parallel data-hubs on our side, where integration for Business use-cases on-top of CDF are interesting for us.General availability of SAP CDC capabilities for Azure Data Factory and Azure Synapse Analytics (microsoft.com)

The newly introduced Documentum Extractor is built against version 7.2.0180.0170 of DFC.Issue users might face when running the jar file with the below commandjava -jar path/to/documentum-extractor-<version>.jar path/to/config.yamlIf a user tried to run the Documentum Extractor with the dfc.jar file with the above command as mentioned in this guide, the user will receive an error message similar to the:Main - Documentum Extractor failed:java.lang.NoClassDefFoundError: com/documentum/fc/common/DfExceptionThis is due to the fact that the Documentum Extractor jar is not identifying the main classpath.Workaround to run the Documentum Extractor with the dfc.jar file.As a workaround users could specify the classpath to include the extractor and run it as shown below.
